- All Implemented Interfaces:
Comparable<SystemIndexDescriptor.MappingsVersion>,Writeable,ToXContent
- Enclosing class:
SystemIndexDescriptor
public static record SystemIndexDescriptor.MappingsVersion(int version, int hash)
extends Record
implements Writeable, ToXContent, Comparable<SystemIndexDescriptor.MappingsVersion>
The version of the mapping, which should be stored as an int in a mapping metadata
field. This will be used with prior index descriptors to determine which mappings
should be used when creating a system index, and it will be used to determine when
mappings should be updated with the latest mappings from the system index descriptor.
See
SystemIndexMappingUpdateService, TransportCreateIndexAction,
and AutoCreateAction.
Version should be a non-negative integer for a managed index, or -1 for unmanaged indices. The hash is a hash of the system index descriptor's mappings so that we can warn in case of inconsistencies across nodes.

toString
Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components. -
hashCode
public final int hashCode()Returns a hash code value for this object. The value is derived from the hash code of each of the record components. -
equals
Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with '=='. -
version
public int version()Returns the value of theversionrecord component.- Returns:
- the value of the
versionrecord component
-
hash
public int hash()Returns the value of thehashrecord component.- Returns:
- the value of the
hashrecord component
